This 'Illegal characters' error is something that my setup is suffering from too. Quite annoying, because my wife is a frequent user of online video's. This is an error that I first saw when I upgraded to MP 1.1.3.
@Offbyone, this has nothing to do with your plugin, right? Any suggestions on how to solve this? Thanks.
BTW: great plugin!
